Example

Example: a phone photo turned into a 307 × 378 px Spanish passport photo

A Spanish national living in Manchester is renewing her passport at the consulate and needs a 26 × 32 mm photo. She takes a portrait on her phone against a plain white wall: photo.jpg, 3024 × 4032 pixels. The page keeps “Fill and crop to 26×32 mm”, output format “Same as original”.

  1. The frame keeps the 26:32 shape and starts centred and as large as it can be: 3024 × 3723 pixels, the full width, with 154 pixels off the top and 155 off the bottom.
  2. Drag and resize it until her head fills most of the height, with a little space above the hair.
  3. Press Resize to 26×32 mm: what is inside the frame is scaled to 307 × 378 pixels and saved as photo-307x378.jpg, marked 300 dpi.

A 307 × 378 px JPG that prints at exactly 26 × 32 mm at 300 dpi. For printed copies, put it on one sheet with the Passport photo print sheet tool at 26×32 mm. If an online form caps the file size, “Keep the file under”, say 50 KB, lowers the quality, never the pixels.

How it works

  1. Drop the portrait onto the box, or pick it from your phone. A plain, light background and a straight look at the camera give the cleanest result.
  2. Fill and crop is preselected, so a frame locked to the 26:32 shape appears on the photo. Drag it over your face and pull a corner until your head and shoulders sit inside with a little space above your hair.
  3. Press Resize to 26×32 mm. The file that comes out is exactly 307 × 378 pixels.
  4. Download it, then print it at 26 × 32 mm or attach it to the form as it is.

Frequently asked questions

Why 307 × 378 pixels?
26 mm ÷ 25.4 × 300 = 307 and 32 mm ÷ 25.4 × 300 = 378. That is the 26 × 32 mm photo of the Spanish DNI and passport at 300 dpi, the resolution print shops work at.
Can I change the proportions?
Not on this page: the size is fixed at 307 × 378, so the crop frame keeps the 26:32 shape and the photo cannot come out stretched. You only choose which part of the picture the frame holds. For a free size, use the main Resize image tool.
Does the file carry a 300 dpi tag?
Yes. A JPG or PNG comes out marked 300 dpi, so photo software opens it at 26 × 32 mm (a WebP file carries no dpi mark). At a print shop, still ask for the physical size rather than trusting what its software shows.
How do I get several copies on one sheet?
Use the Passport photo print sheet tool and choose the 26×32 mm size. It repeats one photo across 4×6 inch, L-size, 5×7 inch or A4 paper at 300 dpi with light cut lines.
Is the DNI photo the same size as the Spanish passport photo?
Yes: both ask for 26 × 32 mm, so one 307 × 378 px file does for both. It is not the size for a UK or US passport — those are 35 × 45 mm and 2 × 2 inches, and have pages of their own.
Can I use a photo taken on my phone?
Yes, as in the example above. A phone photo has far more pixels than needed (3024 × 4032 against 307 × 378), so the frame can be tight on the face and the result is still sharp. Stand facing a plain, light wall in even daylight.
Is my photo uploaded?
No. Cropping and resizing run in your browser, which matters for a document photo. The free plan allows 3 files per run, 20 MB per file and 5 runs a day; Pro removes those limits.
